To all whom it may concern:

' erly understood and readily carried into effeet, we have hereunto appended two sheets of drawings, of which Figure 1 is a front elevation of the machine embodying our invention with parts broken away. Fig. 2 is a partial side elevation and partial section on line II II, Fig. 1. Fig. 3 is a plan of therollers, andFig. 4 is a plan view of the tension device with the cover m removed. All hereinafter more fully described.

In carrying outour invention we provide a suitable bracket or framework A, on which there is carried a pair of fluted rollersB B. The rollers are disposed laterally to each other-that is to say, their axes 'areparallel.

One of the rollers-namely, roller B is provided with twice as many flutes, grooves, or indentations C as the other roller B. The grooves are cut obliquely or helically at different pitches on the two rollers, B having three indentations out approximately at an angle of forty-five degrees and B six indentations cut approximately at an angle of sixty degrees. On this bracket-or framework A above the rollers B B there is also carried a hollow telescoping tube D, in which there is a spindle E, having a weight F on its upper end, while the lower end bears on a spiral spring Gr, placed in the hollow telescoping tube. The bottom of this tube D is in the form of or constitutes a small bifurcated bracket H, on which there is carried a small concave roller I. In front of this bracket H there is a guide-pulley J, carried on a standard over which the rubber passes. A spring tension-clip K for the rubber is also provided. The thread or ribbon of rubber g passes under a bent arm K, which is kept down by the pressure of the spring, which is covered by a piece of leather m.

In use the rubber g, which is unwound from a pair of bobbins N, carried in a bracket 0 beneath the platform or table P, is partially wound on the core by the operator and then passed under the tension-clip K and over the guide-pulley J and the core dropped in between the large rollers B and B. The telescoping tube D, with small roller 1, is then lowered until it rests on the core, when the A power, which may be steam, electric, hand,

or otherwise, is applied. The core by means of the flutes, grooves, or indentations O travels about in difierent directions, and the rubber becomes wound on it, and the graduallyincreasing ball elevates the tube D. The weight F is yieldingly supported by the spring G, which arrangement prevents cutting of the rubber. attained, the tube D, with smaller roller 1, is raised out of the way and held in that position by a suitable clip.

The driving power is transmitted by means of a belt Q to a driving-pulley R, mounted on a central shaft S, upon which is also mounted a loose pulley B. On this shaft S is keyed or otherwise rigidly mounted a coaxial spurwheel T, provided with internal teeth, which engage with and communicate motion -to the spur-pinions U U, rigidly mounted upon the .spindles b b of thefluted rollers B and'B, as

seen in Fig. 2.

It will be seen that the machine comprises two distinct and independent operating appliances.

We claim 1. In machines for winding rubber thread or ribbon on the cores of golf-balls the combination of a pair of grooved or fluted rollers, the grooves, flutes or indentations of the front roller being only half the number of the rear roller and cut at an angle or pitch approximately forty-five degrees while the angle of the grooves of the rear roller is approximately sixty degrees, means for imparting rotation to the rollers, a concave roller carried in a bifurcated bracket and spring actuated for imparting pressure to the core of the ball being wound, a spring tension-clipthrough which'the thread or ribbon passes and a guideroller by'which it is directed to the core sub- When the proper size has been 7 stantially as described and shown on the drawings.

2. In a machine for Winding balls, a pair of rotatable obliquely-grooved rollers disposed laterally to each other spaced apart and adapted to receive the ball between them. v

3. In a machine for Winding balls, a pair of rotatable rollers provided with oblique grooves and adapted to receive the ball between them; the grooves of one of the rollers being of a pitch that is different from the pitch of the grooves of the other roller.

4. In a machine for Winding balls, a pair of rollers provided with oblique grooves and adapted to receive the ball between them, and means for rotating said rollers; the number and pitch of the grooves being dill'erent on the two rollers.

In testimony whereof we allix our signatures in presence of two witnesses.
